"Greens follow Green Leader"

The Drazi decide on a new government every few years with the custom of drawing green and purple scarves from a barrel and then brawling between greens and purples. In the midst of trying to convince the Green Leader to call it off, Ivanova grabs his scarf from him, and is informed that SHE is now the Green Leader. The former Green Leader sheepishly explains, "Rules of combat older than contact with other races. Did not mention aliens. Rules change... caught up in committee. Not come through yet."
